A Composite Insulator is a crucial component in electrical power transmission and distribution systems. It is designed to provide mechanical support and electrical insulation between conductors and transmission structures. Unlike traditional porcelain or glass insulators, composite insulators are made of polymer materials such as silicone rubber, fiberglass-reinforced rods, and metal end fittings.

These insulators offer superior advantages, including lightweight construction, high mechanical strength, excellent resistance to pollution, and superior hydrophobic performance, which helps in preventing flashovers. Composite insulators are widely used in high-voltage applications, such as transmission lines, substations, and railway electrification, ensuring reliable performance even in harsh environmental conditions.
